In the 13th of the same reign, 1285, he had a grant from the son of Gerard de Rodes to himself, his wife and his son, in fee of the manors of Langar and Berneston, in Nottinghamshire. In the 20th of Edward I, being the King's Lieutenant for Wales, he fought and defeated Rees ap Meredith, in a great battle wherein 4000 Welshmen were slain and Rees himself, having been made a prisoner, was conveyed to York and there executed. Robert de Tibetot was subsequently in the wars of Gascony and Scotland.
